Description

The invention relates to a mobile communication system consisting of base station equipment and mobile station equipment, and a mobile communication method.

The level of technology

The International Standardization Project, 3CPP (3rd Generation Partnership Project), discusses the specifications of the network developed from \ U-SIMA (Broadband Code Division Multiple Access) and C8M (Global Mobile Communication System) as the next generation cellular mobile communication system. .

3CRP has been discussing cellular mobile communication systems for a long time and has standardized the \ U-SIMA system as a third-generation cellular mobile communication system. H8IRA (high speed downlink packet access) with a higher connection speed has been standardized and this service is operational. 3CPP is also currently discussing the development of third-generation radio access technology (a long-term development project, hereafter called LTE) and an improved BTU (hereinafter referred to as LTE-A), aimed at further increasing the speed of communication.

The ORIMA method (orthogonal frequency division multiple access) and the 8C-ROME method (frequency division multiple access and single carrier), which perform user multiplexing using subcarriers that are at right angles to each other, are discussed as communication systems in Ate. In particular, the ORIMA method is a multi-carrier communication method and is proposed for the downlink, and the 8C-ROME method is a single-carrier communication method and is proposed for the uplink communication.

On the other hand, for communication methods in LTE-A, it is discussed to introduce an ORIM method for the downlink and a clustered 8C-ROME method (clustered multiple access with frequency division channels and a single carrier, also called IRT-8-ORIM with spectrum management or ORIM with preliminary ИРТ coding), for uplink communication in addition to the method 8С-РИМА. The 8C-RIMA method and the clustered 8C-REMA system. proposed as communication methods on the uplink in LTE and LTE-A, characterized by the fact that RARK (peak-to-average power ratio) during data (information) transmission can be lowered to a lower level.

While a typical mobile communication system uses a continuous frequency band, for LTE-A it is discussed to use a variety of continuous / non-continuous frequency bands (hereinafter referred to as carrier elements, carrier components (CC) or elementary carriers, component carriers (CC)) in a composite way, to implement the operation as a single frequency band (wider frequency band) (frequency band aggregation, also called spectrum aggregation, carrier aggregation and frequency aggregation). It is also proposed to give different frequency bands to the frequency band used for downlink communication and the frequency band used for uplink communication so that the base station equipment and the mobile station equipment more flexibly use a wider frequency range to communicate ( asymmetric aggregation of frequency bands: asymmetric carrier aggregation) (Non-Patent Literature 1).

FIG. 8 is a diagram for explaining the aggregation of frequency bands in the conventional method. The provision of the same frequency band to the frequency band used for downlink communication (HB) and the frequency band used for uplink communication (HL), as shown in FIG. 8, also referred to as symmetric aggregation of frequency bands (symmetric carrier aggregation). As shown in FIG. 8, the base station equipment and the mobile station equipment use a plurality of component carriers that are continuous / non-continuous frequency bands in the composite method, thus performing communication in a wider frequency range composed of a plurality of component carriers. In this case, by way of example, it is shown that the frequency band used for downlink communication with a frequency band of 100 MHz (hereinafter also referred to as the frequency band of the IB system or the frequency band of the IB system) is composed of five component carriers (ICS1: component carrier 1 downlink, ISS2, ISS3, ISS4 and ISS5) each having a frequency band of 20 MHz. By way of example, it is also depicted that the frequency band used for uplink communication with a frequency band of 100 MHz (hereinafter also referred to as the frequency band of the system IB or the system bandwidth ib) is composed of five component carriers (ICN1: component carrier 1 of the uplink communications, ISS2, ISS3, ISS4 and ISS5), each having a 20 MHz frequency band.

FIG. 8, downlink channels, such as a physical downlink control channel (hereinafter, RISCH) and a physical downlink shared channel (hereinafter, RI8SN) are mapped to each of the downlink component carriers. And the base station equipment uses the RISCH to transmit control information to the mobile station equipment for transmitting the downlink transport block transmitted by using the RIS8CH on each of the downlink component carriers (such as resource assignment information, MS8 information modulation and coding) and the NACO (hybrid automatic repeat request) process information) (uses ROSSI to assign the R-8SN to the equipment of the mobile station), and uses the R-8SN to Pass the transport block of the downlink to the mobile station apparatus.

Uplink channels such as an uplink physical control channel (hereinafter, RISCH) and an uplink physical shared channel (hereinafter, RIS8CH) are mapped to each of the uplink component carriers. And the equipment of the mobile station uses RISCH and / or RI8SN on each of the uplink component carriers to transmit NACO control information (hereinafter described as NACO control information) for the RISCH and / or downlink transport block to the base station equipment. The NACO control information includes a signal (information) indicating an ACK / IASK (positive acknowledgment / negative acknowledgment, ACK signal or IASK signal) and / or a signal (information) indicating ITX (discontinuous transmission) for RISCH and / or transport block communication lines. ITH is a signal (information) indicating that the mobile station equipment cannot detect the RISCH from the base station equipment (or it can be a signal (information) indicating whether the mobile station equipment can detect the RISCH). FIG. 8, any of the downlink / uplink channels such as RISCH, RIS8SN, RISCH and RI8SN may not be mapped to some downlink / uplink component carriers.

Similarly, FIG. 9 is a diagram for explaining asymmetric aggregation of frequency bands in the conventional technique. As shown in FIG. 9, the base station equipment and the mobile station equipment give different frequency bands to the frequency band used for downlink communication and the frequency band used for uplink communication, and use the component carriers constituting these frequency bands in a composite way, thus performing communication in a wider range of frequencies. In this case, by way of example, the frequency range used for downlink communication in the 100 MHz frequency band is composed of five downlink component carriers (ISS1, ISS2, ISS3, ISS4, and ISS5), each having a frequency band of 20 MHz. and that the frequency band used for uplink communication with the 40 MHz frequency band is composed of two component carriers (ICS1 and ICS2), each having a frequency band of 20 MHz. FIG. 9 channels of the downlink / uplink are mapped to each of the downlink / uplink component carriers. And the equipment of the base station uses RIS8N, assigned by RISCH, to transmit the transport block to the equipment of the mobile station. And the equipment of the mobile station uses this RISN and / or this RI8SN to transmit information management NAKO to the equipment of the base station.

In order to transmit NACO control information for transmitting RISCH and / or RI8SN channels on a plurality of downlink component carriers, the mobile station equipment must transmit information to the base station equipment indicating the ASC, IASK and ITX for the RISCH and / or RI8SN transmitted on each of the component bearing For example, if the base station equipment transmits RISCH and / or RI8SN channels on five downlink component carriers, the mobile station equipment must provide information indicating as defined in any of the ASC, IASK and ITH, and therefore must transmit information capable of indicating the fifth power of three types of state (243 types of state), per base station equipment. To represent these types of state as bit information, eight bits (capable of providing 256 types of state) are required as information bits.

Non-Patent Literature 2 proposes a transmission method in which the base station equipment assigns multiple RISCH resources to the mobile station equipment to transmit NACO control information in such a way that the mobile station equipment selects one RISCH resource from the assigned RISCH resources to transmit the NACO control information to the base station equipment use of the selected resource RISSN. For example, the base station equipment assigns RISCH resources to the mobile station equipment corresponding to the respective RIS8CH channels transmitted on the plurality of downlink component carriers, and the mobile station equipment selects one RISCH resource from the multiple RISCH resources to transmit the NACCO control information by using the selected RISCH resource. The base station equipment extracts the RISCH resource selected by the mobile station equipment, in addition to the bit information transmitted by the mobile station equipment, in order to transmit / receive information indicating the NACO control information between the base station equipment and the mobile station equipment.

Summary of Invention

A problem that must be solved in accordance with the invention.

However, in the conventional method, a large number of parts of the control information (uplink control information, IS1) must be exchanged between the base station apparatus and the mobile station apparatus in addition to the NACTS control information, and these portions of the control information cannot be efficiently transmitted / received.

Since CTE-A involves transmission on a plurality of component carriers, a large number of pieces of control information need to be transmitted, and these pieces of control information must be efficiently transmitted / received. However, in the conventional method, for example, the base station equipment must often assign both an uplink resource for transmitting NACO control information and an uplink resource for transmitting other control information. For example, if the timing of the transmission of the NACO control information to the base station equipment coincides with the timing of the transmission of other control information, the equipment of the mobile station should suspend (postpone, terminate) the transmission of the NACO control information or other control information. In particular, in the event that the transmission of parts of the control information is suspended (delayed, terminated), the equipment of the mobile station must use the uplink resource of the next clocking assigned by the base station equipment to transmit these parts of the control information. Therefore, the conventional method has the problem of reducing the capacity of a mobile communication system.

The present invention was conceived in view of these situations, and therefore it is an object of the present invention to provide a mobile communication system and a mobile communication method in which the base station equipment and the mobile station equipment effectively transmit NACCH control information, as well as other control information in the case of performing communication through the use of wide frequency range composed of multiple component carriers, thus preventing a reduction in the capacity of a mobile communication system and.

Modes for carrying out the invention

Embodiments of the present invention are described below with reference to the drawings. FIG. 1 is a diagram of one exemplary channel configuration of an embodiment of the present invention. The downlink physical channels are made up of a physical broadcast channel (RVSN), RISCH, RI8SN, and a physical channel of the hybrid APO indicator (PH1CH). Uplink physical channels are composed of RIS8SN and RISCH.

The PBCH displays a broadcast channel (BCH) at intervals of 40 ms. Blind detection is performed for clocks of 40 ms. Therefore, explicit signaling is not performed to represent clocking. A subframe including the PBCH can be decoded separately (self-decoding).

RISCH is a channel used to transmit downlink control information. RISCH is a channel used to notify mobile station equipment regarding the assignment of RI8SN resources, uplink transmission grant, which is the assignment of resources for HAPP information for downlink data, and uplink transmission grant, which is the assignment of RI8CH resources. The RISCH is made up of a plurality of CCEs, and the equipment of the mobile station detects the RISCH composed of these CCEs to receive the RISCH from the base station equipment. The CCE is composed of a plurality of groups of resource elements (KEOs, also called mini-CCEs) distributed in the frequency and time domains. A resource element is a resource block composed of one ORIM character (time component) and one subcarrier (frequency component), and, for example, KEO is composed of four downlink resource elements that are consecutive in the frequency domain, with the exception of the downlink pilot channel in the frequency domain in the same ORIM symbol. For example, one RISCH is composed of one, two, four, and eight CCEs with consecutive numbers identifying these CCEs (CCE index).

RISCH is separately encoded (subjected to separate coding) according to the equipment and type of mobile station. Thus, the mobile station equipment detects a plurality of RISCH channels and obtains a downlink or uplink resource assignment and information indicating other control information. The value of the SCS (redundant cyclic code check) is transmitted at each RISCH, and the equipment of the mobile station performs the SCS for each set of CCE elements that can make up the RISCH and receives the RISCH of the successful CEC. This is referred to as blind decoding and with respect to the set of CCE elements that may constitute RISCH, which is blindly decoded by the mobile station, its range is referred to as search space. Thus, the equipment of the mobile station performs blind decoding for CCE elements in the search space in order to detect RISCH.

If the assignment of RI8SN resources is transmitted to the RISCH, the equipment of the mobile station uses this RI8SN to receive the downlink signal (data) (downlink data (downlink shared channel (IB-8CH)) and / or downlink control data ) in accordance with the assignment of resources specified by RISCH from the base station equipment. Thus, RISCH is used to transmit a signal that assigns resources to a downlink (hereinafter referred to as a downlink transmission enable signal or downlink provision). If the assignment of the RIS8SN channel resources is transmitted to the RISCH, the mobile station equipment uses this RI8SN to transmit the uplink signal (data) (uplink data (shared uplink channel (IE-8CH)) and / or uplink control data communication) in accordance with the assignment of resources specified by RISCH of the base station equipment. Therefore, RISCH is used for transmitting a signal permitting data transmission to the uplink (hereinafter referred to as an uplink transmission enable signal or uplink provision).

RI8SN is a channel used to transmit data downlink (shared channel downlink (IE-8CH)) or paging information (paging channel (PCH)). Downlink data (downlink shared channel (IE-8CH)) indicates the transmission of user data, for example, and IE-8CH is a transport channel. IE-8SN supports NACC and dynamic adaptive control of the radio line. IE-8CH supports dynamic resource assignment and quasi-static resource assignment.

RI8SN is the channel mainly used for data transmission uplink communication (shared channel uplink communication: iR-8SN). If the base station apparatus schedules the mobile station apparatus, the uplink control data (control information, uplink control information) is also transmitted by using the RIS8CH. This uplink control data includes channel state information C81 (channel state information or channel statistical information), downlink channel quality indicator C '.' P1, pre-coding matrix indicator PM1, rank indicator K1, and NACTS control information for transmission signal downlink (transport block downlink). The control information of the NARP for downlink signaling includes information indicating ASC / YLSC and / or information indicating РО for the ROSSA channels and / or downlink transport blocks. ΌΤΧ is information indicating that the equipment of the mobile station cannot detect ROSSI from the equipment of the base station. In RI8SN, the data is transmitted to the base station equipment after adding the 24-bit SCS code generated by using a predetermined generator polynomial from data to be transmitted via RI8SN (downlink transport blocks).

Uplink data (IL-8SN) and downlink data (OBH-CHS) may include a radio resource control signal exchanged between the base station equipment and the mobile station equipment (hereinafter referred to as CCR signaling: radio resource control signaling), elements MAC control (media access control), etc. The CCS signaling indicates signals exchanged through a higher level (radio resource control level) between the base station equipment and the mobile station equipment.

RISCH is a channel used to transmit uplink control data (control information, uplink control information). Uplink control data includes a scheduling request, for example, a scheduling request is used by the mobile station's equipment to transmit the RI8SN transmission request to the base station equipment. That is, the equipment of the mobile station transmits a scheduling request to the equipment of the base station in the case of requesting the assignment of resources for transmitting uplink data (requesting transmission through I-8CH).

In this case, if the base station equipment and the mobile station equipment perform communication by using a plurality of component carriers, a scheduling request is transmitted from the mobile station equipment in case the mobile station requests resource allocation for uplink data transmission on the plurality of uplink component carriers. In other words, the equipment of the mobile station transmits a scheduling request to the equipment of the base station so as to make a request for transmission over RI8SN channels on a plurality of uplink component carriers. In the case of receiving a scheduling request from the mobile station equipment, the base station equipment assigns resources on a plurality of uplink component carriers to the mobile station equipment taking into account the status of resources in the controlled cell, etc.

Thus, for example, in the case where the base station equipment and the mobile station equipment communicate by using two uplink component carriers (ICN1 and ICIS2 in FIG. 9), the mobile station apparatus sends a scheduling request to request resources (eg, channels RI8SN) for data transmission uplink communication on ISS1 and / or ISS2 from the equipment of the base station. In the case of receiving a scheduling request from the mobile station equipment, the base station equipment assigns resources (eg, RI8SN channels) for transmitting uplink data on the ISS1 and / or ISS2 to the equipment of the mobile station, taking into account the status of resources in the controlled cell, etc.

Uplink control data includes channel state information C81 (channel state information or channel statistical information), downlink channel quality indicator SC1, pre-coding matrix indicator PM1, and rank indicator K1 transmitted (returned) from the mobile station equipment to the equipment base station.

ASC and LSK are used for NLCC. NLCC combines automatic retransmission request (LCC) with error correction coding, such as turbo coding, to provide error management. For example, in the case of a NAC using a chain combining (CC), when an error is detected in the receive packet, a retransmission of the entire same packet is requested, and the two receive packets are combined to improve the reception quality. In the case of an NABC using incremental redundancy (1K), since the redundancy bits are separated and the divided bits are sequentially re-transmitted bit by bit, the encoded transfer rate decreases when the number of retransmissions increases, thus ensuring improved error correction capability.

At RISCH, code expansion is performed in the frequency direction using the CA2AC sequence (constant amplitude and zero autocorrelation) having a sequence length of 12 in the frequency direction (12 subcarriers) and time direction (for estimating the propagation channel) for one scheduled block (two resource blocks ). The CA2AC sequence is a sequence having a constant amplitude and excellent autocorrelation characteristics in the time and frequency domains. Due to the constant amplitude in the time domain, PARC (peak-to-average power ratio) can be lowered to a lower level. For example, at the RISCH, multiplexing of users can be achieved by providing a cyclic shift (cyclic delay) for a CA2AC sequence having a length of 12. When NACTC control information is transmitted, the block code allows the use of a code extended in the time domain and, in particular, Walsh code can be used having a sequence length of four. As described above, when NACN control information is transmitted, the RISCH resources allow to achieve

- 8 022843 user multiplexing by using codes in the same time and frequency resources.

The first embodiment.

The following describes the first embodiment of a mobile communication system using a base station apparatus and a mobile station apparatus. In the first embodiment, the base station equipment assigns the mobile station equipment a resource for transmitting the NACO control information through the mobile station equipment, and the mobile station equipment uses the assigned resource to transmit the NACO control information for the RESSN channels and / or RBMS channels to the base station equipment. transmitted on multiple downlink component carriers, as well as a scheduling request requesting an assignment. resources for uplink data transmission.

The base station equipment assigns a resource to the mobile station equipment for transmitting the scheduling request by the mobile station equipment and also assigns the mobile station equipment a resource for transmitting the NACA control information through the mobile station equipment, and the mobile station equipment uses this resource to transmit control information to transmit to the base station equipment NACO control station information for RESSN channels

- 11 022843 and / or ΡΌδΡΌ channels transmitted on the set of downlink component carriers, as well as a scheduling request requesting the assignment of resources for the transmission of uplink data.

In this case, the equipment of the mobile station refers to one table combining the control information ΗΛΗ and the scheduling request. In particular, the mobile station equipment refers to one table combining the NLRM control information and the scheduling request, and selects a bit sequence corresponding to the NLRR control information and the scheduling request from the table that is addressed to transmit the selected bit sequence to the base station equipment.

The table that indicates the bit sequence corresponding to the NLRr control information for the NESSN and / or the ΡΌδΟΗ channels on the set of downlink component carriers and the scheduling request may vary depending on the number of downlink component carriers used for communication. In particular, the table that indicates the bit sequence corresponding to the NLRD control information and the scheduling request may be different depending on the number of downlink component carriers used for communication established by the base station apparatus. If the scheduling request is transmitted to ΡυδΟΗ, it is assumed that the mobile station equipment transmits the scheduling request to the base station equipment in advance, and that the ΡυδΟΗ resource is assigned from the base station equipment.

Although the frequency range is defined in the frequency band (Hz) in the first embodiment, the frequency range can be determined in the number of resource blocks (PB) composed of frequency and time. Component carriers (hereinafter also referred to as carrier components, element carriers, or carrier elements) in this embodiment are (narrower) aggregated frequency bands if this base station equipment and mobile station equipment perform communication by using a wider frequency range ( or frequency range of the system). Base station equipment and mobile station equipment can aggregate multiple component carriers to form a wider frequency range and use multiple component carriers in a complex way, thus realizing high-speed data transmission (information transmission / reception) (aggregation of frequency bands described above). For example, the base station equipment and the mobile station equipment can aggregate five component carriers having a frequency band of 20 MHz to constitute a wider frequency band having a frequency band of 100 MHz, and use these five component carriers in a complex way to communicate.

The component carrier indicates each of the (narrower) frequency bands (eg, frequency bands having a frequency band of 20 MHz) constituting this wider frequency band (eg, a frequency band having a frequency band of 100 MHz). The component carrier also indicates the (center) carrier frequency of each of the (narrower) frequency ranges constituting this wider frequency range. Thus, the downlink component carrier has a frequency range (width) of a portion of the frequency range used by the base station equipment and a mobile station equipment during the transmission / reception of a downlink signal, and the uplink component carrier has a frequency range (width) of the range frequencies used by the base station equipment and the mobile station equipment during the transmission / reception of the uplink signal. A component carrier can be defined as a component unit (block) of a certain physical channel (for example, ΡΌΟΟΗ, ΡΌδΟΗ, ΡυΟΟΗ and Ρυδ).

Component carriers may be mapped to continuous frequency bands or mapped to non-continuous frequency bands, and a wider frequency band, established by aggregating a plurality of component carriers that are continuous and / or non-continuous frequency bands. The frequency range (or the downlink system bandwidth or the downlink system bandwidth) used for downlink communication composed of downlink component carriers may not necessarily have the same frequency band as the frequency band (or uplink system range or uplink system bandwidth) used for uplink communication made up of uplink component carriers. Even if the frequency band used for downlink communication and the frequency band used for uplink communication have frequency bands that are different from each other, the base station equipment and the mobile station equipment can use component carriers in a complex way to perform communication (asymmetric aggregation of frequency bands, described above).

FIG. 4 shows an example of a mobile communication system to which the first embodiment is applicable. FIG. 4 depicts that the frequency band used for downlink communication having a frequency band of 100 MHz is composed of five downlink component carriers (ESSE ESS2. ESS3, ESS4 and ESS5). each having a frequency band of 20 MHz, and that the frequency band used for uplink communication, which has a frequency band of 100 MHz, is composed of five uplink component carriers (up-to-date uplink (ISS1, ISS2, ISS3, ISS4, and ISS5), each having a frequency band of 20 MHz. FIG. 4 channels of the downlink / uplink are mapped to each of the downlink / uplink component carriers. FIG. 4, any of the downlink / uplink channels, such as RISCH, RIBSN, RISCH and RI8SN, may not be mapped to some downlink / uplink component carriers.

FIG. 4, the base station equipment may use the RISCH on the downlink component carrier to assign the RIS8CH. FIG. 4, by way of example, it is shown that the base station equipment uses RISCH at ISIS 1 (RISCH indicated by diagonal lines) to assign an RBIB to ISS1 (RBIB of ISS1 is assigned by RISCH indicated by diagonal lines in ICN1).

FIG. 4, the base station equipment may transmit the RISCH to the mobile station on the downlink component carrier, together with information representing the component carrier indicator, to assign the RIBCH to the downlink component carrier or the same or different downlink component carrier, to which the RISCH is mapped. FIG. 4 depicts that the base station equipment transmits to the equipment of the RISCH mobile station, indicated by diagonal lines on the PSP, along with information representing the component carrier indicator, indicating that RIBCH has been assigned to PIS4. The base station equipment can transmit to the equipment of the RISCH mobile station, indicated by diagonal lines on the ISSE, together with information representing the component carrier indicator, indicating that the RIBSN is assigned to the ESSE. with information representing the component carrier indicator, indicating that the REIB has been assigned to the PILV.

FIG. 4, the base station equipment can use multiple RISCH channels on downlink component carriers to assign multiple RIBSN channels in the same subframe. FIG. 4 shows by way of example that the base station equipment uses three RISCH channels on ISS1 and TISS3 (RISCH channels, respectively, indicated by diagonal lines, horizontal lines and grid lines) to indicate that the RIBSN channels are assigned to the ESSA of the TESIS and ISSS4 (the RIBSN on the ISSS1 is assigned by RISCH, indicated by diagonal lines on ISSS; RIBSN on PSS, assigned by RISCH, indicated by horizontal lines on PSS; and RI8SN on ISS, assigned by RISCH, marked by grid lines on PSS. The base station equipment may use the RIS8CH channels on the ISS1, the ISSZ and ISS4 to transmit (up to three) downlink transport blocks to the equipment of the mobile station in the same subframe.

FIG. 4, the mobile station equipment uses the corresponding R-8CH channels on the uplink component carriers to transmit a plurality of uplink transport blocks to the base station equipment in the same subframe. For example, the equipment of the mobile station uses five RI8SN channels on ISSI, ISS2, ISSZ, ISS4 and ISS5 to transmit (up to five) uplink transport blocks to the base station equipment in the same subframe.

FIG. 4, the mobile station equipment transmits to the base station equipment the NLRS control information for the RISCH channel (s) and / or downlink transport block (s) transmitted from the base station equipment. For example, the equipment of the mobile station transmits to the base station equipment information management NLRS for five RISCH channels and / or five downlink transport blocks transmitted in the same subframe from the base station equipment.

FIG. 4, the base station equipment assigns the RISCH resource to the mobile station equipment for transmitting NLRS control information through the mobile station equipment. For example, the base station equipment can use the PPC signaling to assign the RISCH resource to the mobile station equipment for transmitting control information to the FLRS via the mobile station equipment.

For example, base station equipment can assign a RISCH resource for transmitting control information to LDCs by means of the mobile station equipment for each RIN8CH transmitted on downlink component carriers. In particular, the base station equipment can assign a RISCH resource for transmitting NLRS control information through the mobile station equipment corresponding to the RISCH, which assigns the RIS8CH transmitted on the downlink component carrier (for example, the position of the RISCH in the RISCH resource area).

The equipment of the base station can set a lot of RISCH resources for the equipment of the mobile station. And the base station equipment can indicate one RISCH resource from a variety of RISCH resources in order to allocate a RISCH resource for transmitting NLRS control information through the mobile station equipment. For example, base station equipment can use PPC signaling to set up multiple RISCH resources. And the equipment of the base station can transmit information indicating one RISCH resource from the RISCH resource set by using this RISCH. And the base station equipment can assign the RISCH resource to the mobile station equipment for transmitting the NACF control information through the mobile station equipment.

For example, base station equipment can use CCS signaling to establish four RISCH resources. And the equipment of the base station can transmit information indicating one RISCH resource from among the four RISCH resources by using the RISCH. And the equipment of the base station can assign (specify) this one resource of the RISCH to the equipment of the mobile station. Since the base station equipment assigns a RISCH resource for transmitting NACF control information in this manner, this RISCH resource can be flexibly specified to the mobile station equipment.

FIG. 4, the base station equipment can use the CCN signaling to assign the RISCH resource to the mobile station equipment for transmitting the scheduling request by the mobile station equipment. For example, the base station equipment may periodically assign a RISCH resource to the mobile station equipment for transmitting a scheduling request by the mobile station equipment. In this case, since the equipment of the mobile station transmits 8K by using the RISCH resource for transmitting the NACF control information assigned by the base station equipment, the RISCH resource periodically assigned by using CCS signaling can be reduced and the radio resource can be effectively used.

FIG. 4, the equipment of the mobile station uses the RISCH resource assigned by the base station equipment to transmit control information to NACF. In particular, the equipment of the mobile station uses the RISCH assigned by the base station equipment to transmit NACF control information for the RISCH channels and / or RI8SN channels (or downlink transport blocks) transmitted on the plurality of downlink component carriers.

FIG. 4, if the scheduling request is transmitted to the base station equipment, the mobile station equipment can transmit the scheduling request along with the NACF control information to the base station equipment. In particular, the equipment of the mobile station can transmit both the NACF control information and the scheduling request by using the RISCH resource assigned by the base station apparatus for transmitting the NACF control information.

Thus, the mobile station equipment can transmit to the base station equipment NACF control information for RISCH channels and / or RIS8CH channels transmitted on a plurality of downlink component carriers, as well as a scheduling request requesting resource assignment for transmitting uplink data on a plurality of component uplink carriers. In this case, the equipment of the mobile station transmits the scheduling request along with the NACF control information by using the RISCH resource assigned by the base station apparatus for transmitting the NACF control information.

FIG. 5 is a sequence diagram of operations in case the equipment of the mobile station transmits a scheduling request along with control information of the NACF to the equipment of the base station. First, the base station equipment assigns a resource to the mobile station equipment for transmitting the NACF control information to the mobile station equipment (501). The base station equipment may assign a resource to the mobile station equipment for transmitting a scheduling request by the mobile station equipment. For example, the base station equipment uses KKS signaling to assign the RISCH resource to the mobile station equipment for transmitting the NACF control information through the mobile station equipment. In addition, for example, the base station equipment uses the CCN signaling to assign the RISCH resource to the mobile station equipment for transmitting the scheduling request by the mobile station equipment. The base station equipment can dynamically assign a RISCH resource depending on the position of the RISCH transmitted to the mobile station equipment in the RISCH resource area. The base station equipment may use the CCN signaling to establish a plurality of RISCH resources for the mobile station equipment, and may transmit information indicative of one RISCH resource from the plurality of RISCH resources by using the RISCH. And the base station equipment assigns the RISCH resource to the mobile station equipment. Although the base station equipment assigns a RISCH resource as a resource for transmitting NACF control information through the mobile station equipment in the description of FIG. 5, the base station equipment can assign the RI8SN resource as a resource for transmitting the NACF control information through the mobile station equipment.

The base station equipment then uses the R-8CH channels to transmit downlink transport blocks to the mobile station equipment (502). For example, the base station equipment uses the R-8CH channels on a plurality of downlink component carriers to transmit a plurality of downlink transport blocks to the mobile station equipment in the same subframe. The base station equipment can use multiple RISCH channels to assign multiple RI8CH channels to the mobile station equipment in the same subframe.

Base station equipment can install (number) downlink component carriers used to communicate with mobile station equipment. FIG. 5, by way of example, it is assumed that the base station equipment configures the setting of the parameters for the mobile station equipment so that communication is performed by using two downlink component carriers. Thus, as an example, it is assumed that the base station equipment uses the corresponding RI8SN channels on two downlink component carriers (i.e., uses two DRIZCH channels) to transmit two downlink transport blocks to the mobile station equipment in the same subframe .

Component downlink carriers used for communication established by base station equipment include downlink component carriers activated by base station equipment. In particular, the base station equipment can install downlink component carriers used to communicate with the mobile station equipment, and can also activate downlink component carriers that are likely to be scheduled by the base station equipment. For example, base station equipment may use CCS signaling to establish downlink component carriers used for communication. For example, base station equipment may use MAC signaling to activate downlink component carriers, which are likely to be scheduled by the base station equipment. In the following description, for simplicity, it is described that the base station apparatus installs downlink component carriers used for communication; however, these downlink component carriers include downlink component carriers established by base station equipment using CCS signaling, for example. These downlink component carriers also include downlink component carriers activated by base station equipment using, for example, MAC signaling.

Mobile station equipment displays NACTC control information for transmitting the ROSSN channels and / or RI8SN channels (or downlink transport blocks) from the base station equipment and a scheduling request for the resource assigned by the base station equipment (to the RISCH resource in this case) (503) . The RISCH resource for which the NACCP control information and the scheduling request are mapped by the mobile station equipment is the RISCH resource assigned to the mobile station equipment by the base station equipment for transmitting the NACTS control information. The equipment of the mobile station generates NACO control information based on the reception status of the RIS8CH channels (or downlink transport blocks), and maps the NACCH control information to the RISCH.

The equipment of the mobile station uses the RISCH resource assigned by the base station equipment to transmit NACCH control information and scheduling request (504). The error correction code can be added to the NACCH control information transmitted from the equipment of the mobile station to the equipment of the base station. The base station equipment receives the NACTS control information and the scheduling request transmitted from the mobile station equipment and retrieves these pieces of information (505). If the error correction code is added to the NACCH control information transmitted from the mobile station equipment to the base station equipment, the base station equipment performs decoding in accordance with the encoding method thereof. The base station equipment re-transmits the downlink transport blocks to the mobile station equipment based on the extracted information (NACO control information). The base station equipment assigns a resource for transmitting uplink data to the mobile station equipment based on the extracted information (scheduling request). The base station equipment may assign uplink resources to the mobile station equipment on a plurality of uplink component carriers (eg, a plurality of RIS8CH resources in a plurality of uplink component carriers).

Thus, the mobile station equipment uses the RISCH resource assigned to transmit NACCH control information through the base station apparatus to transmit NACCH control information for the RISCH channels and / or RIS8CH channels transmitted on a plurality of downlink component carriers.

If the scheduling request is transmitted in this case, the mobile station equipment transmits NACCH control information for the RISCH channels and / or RIS8CH channels transmitted on the plurality of downlink component carriers, as well as the scheduling request to request resource assignment for uplink data transmission on the set component carrier uplink communication.

In particular, the mobile station equipment can transmit both the NACCH control information and the scheduling request, even if the NACC control information is transmitted during clocking (in a subframe) periodically assigned to transmit the scheduling request by the base station apparatus. If the transmission of the scheduling request coincides in the subframe (in time) with the transmission of information to the NACO control, the equipment of the mobile station transmits both the control information to the NACO and the scheduling request to the base station equipment. The equipment of the mobile station may use the resource of RISCH assigned to transmit the NACO control information through the base station equipment to transmit both the NACO control information and the scheduling request to the base station equipment.

For example, the mobile station apparatus transmits both the NACO control information and the scheduling request to the base station apparatus with reference to a table combining (in other words, combining, multiplexing or interconnecting) the NACO control information and (information indicating) the scheduling request. For example, the mobile station equipment refers to one table combining the NACO control information and the scheduling request, and selects a bit sequence corresponding to the NACO control information and (information indicating) the scheduling request to transmit the selected bit sequence to the base station equipment. Thus, the mobile station apparatus can transmit both the NACO control information and the scheduling request to the base station apparatus by transmitting a single bit sequence, the corresponding NACO control information and the scheduling request, to the base station apparatus.

FIG. 6 depicts an example of a table combining the NACO control information and (information indicating) a scheduling request. In the table shown in FIG. 6, by way of example, the NACO control information and (information indicating) the scheduling request are presented (composed of) bit fields of 6 bits. In particular, in the table shown in FIG. 6 by way of example, the bit field for the NACO control information (a bit field indicating the NACO control information) is represented by a field of 5 bits from the beginning, and the bit field for (information indicating) a scheduling request is represented by a field of one last bit. In other words, in the table shown in FIG. 6, the bit field for the NACO control information and the bit field for the scheduling request are independently prepared. Both the NACO control information and the scheduling request are mapped to the corresponding bit fields.

By way of example, the table shown in FIG. 6, is shown as a table when the base station equipment configures the setting (parameters) for the mobile station equipment so that communication is performed by using three downlink component carriers. In other words, the table shown in FIG. 6 is a table that represents a combination of NACO control information and scheduling request as a bit sequence in the case where the number of downlink component carriers is three (LHD number 3). By way of example, the table shown in FIG. 6 is depicted as a table used in the case that communication is performed by using three downlink component carriers; however, another table may be used if the base station equipment and the mobile station equipment communicate by using a different amount (other than three) downlink component carriers (for example, four downlink component carriers).

In the table shown in FIG. 6, five bits from the beginning indicate the bit field for the NACO control information, and the last one bit indicates the bit field for the scheduling request (8K). In particular, for example, in the bit sequence 001110, the bit field 00111 of five bits from the beginning indicates the NACO control information, and the last one bit 0 indicates the information that indicates the scheduling request (WITHOUT 8K). For example, in a bit sequence 111111, a bit field 11111 of five bits from the beginning indicates the NACO control information, and the bit field 1 of the last one bit indicates information indicating a scheduling request (C 8K). WITHOUT 8K indicates that the mobile station equipment does not request the base station equipment to assign a resource for uplink data transmission. C 8K indicates that the mobile station equipment is requesting the base station equipment to assign a resource for uplink data transmission. Thus, the mobile station equipment can notify the base station equipment of both states without requesting a resource assignment for transmitting uplink data (a negative state) and requesting a resource assignment (a positive state).

For example, A / MA in the table in FIG. 6 indicates portions of the NACO control information for the R-8CH (or downlink transport blocks) on the respective downlink component carriers. In this example, A, N and Ό denote the ASC, MASK and ITH, respectively. For example, A / MA in the table according to FIG. 6 indicates ACK for RI8SN on some downlink component carrier (for example, ICN1), MASK for RI8CN on some component downlink component carrier (for example, ICN2), and ACK for RI8CN on some component downlink component carrier (for example, ICN3) .

As described above, in the case of transmitting both the NACO control information and the scheduling request to the base station equipment, the mobile station equipment refers to the table, as shown in FIG. 6, and selects a bit sequence corresponding to the NACO control information and (information indicating) the scheduling request from the table referenced to

- 16 022843 transmit the selected bit sequence to the base station equipment.

For example, if the NACO control information for the RE8SN channels (or downlink transport blocks) transmitted on the three downlink component carriers (for example, ESSE ESS2 and ESS3) by the base station equipment is A / Ν / Ν (for example, control information NACO for the RO8CH transmitted on the ESS is ACK; the control information of NACO for the PO8CH is transmitted to the ESS2; is NАСΚ; and the control information of NAKO for the Po8CN transmitted on the ESS3 is NAC), and transmitted from The sequence 100101 per base station equipment.

A table combining the NACO control information and the scheduling request, as shown in FIG. 6, determined in advance in accordance with specifications, etc. The table as shown in FIG. 6 may be installed by the base station equipment for the mobile station equipment using CCN signaling, for example. Base station equipment and mobile station equipment can share a table, as shown in FIG. 6, in advance.

Similarly, FIG. 7 depicts an example of a table combining the NACO control information and (information indicating) a scheduling request. As in the case of the table shown in FIG. 6, the NACO control information (ACK, NACΚ and ΌΤΧ) and (information indicating) the scheduling request are multiplexed and presented as one bit sequence (the 8-bit sequence in this example) in the table shown in FIG. 7. Thus, one bit sequence (the 8-bit sequence in this example) indicates the management information of NACO and (information that indicates) the scheduling request. HCC number 2 in FIG. 7 indicates that the base station equipment uses two downlink component carriers to perform communication for the mobile station equipment. HCC number 3 in FIG. 7 indicates that the base station equipment uses three downlink component carriers to perform communication for the mobile station equipment.

FIG. 7 depicts bit sequences that indicate a combination of NACO control information and scheduling request in (part) cases where the number of downlink component carriers used for communication established by the base station apparatus is two and three. The bit length (also referred to as a codeword) that indicates the NACO control information is the same (bit length of eight bits) regardless of the number of downlink component carriers.

FIG. 7, for example, A / Ν in the case of a downlink component carrier number of two, indicates the NACO control information for the RE8CN channels (or downlink transport blocks) in the respective component carriers and indicates the ACK for the RE8CH on some downlink component carrier (for example, ESSI) and NАСК for РЭ8СН on some downlink component carrier (for example, ОСС2).

FIG. 7, for example, A / Ν / Ό, in the case of three downlink component carriers, indicates the NACO control information for the RE8CN channels (or downlink transport blocks) on the respective component carriers and indicates the ACK for the RE8CH on some component downlink carrier communication lines (for example, OCC1), NАСК for РЭ8СН on some downlink component carrier (for example, ОСС2) and ΌΤΧ for РР8СН on some downlink component carrier (for example, ОСС3).

FIG. 7, if the number of downlink component carriers is two, WITHOUT 8K and C 8K are assigned to the corresponding states of the NACO control information (states from A / A to /). If the number of downlink component carriers is three, the bit sequences 10101111-11000101 are respectively assigned to A / A / E-MA / K. These bit sequences are the same bit sequences as A / A, C 8K-H / H, C 8K in the case of the number of downlink component carriers equal to two. Although bit sequences 11010000-10011110 are not used to indicate the NACO control information and / or 8K presence in the case of a number of downlink component carriers equal to three in FIG. 7, these bit sequences may be used to indicate the NACO control information and / or 8K presence.

By specifying unused bit sequences as NACO control information, as well as scheduling request, depending on the number of downlink component carriers installed by the base station equipment, the amount of information transmitted by the mobile station equipment can be increased without increasing the number of transmitted bits . The base station equipment can determine the status of the NACO control information and the presence of the scheduling request depending on the number of installed (activated) downlink component carriers.

As described above, the transmission / reception of bit sequences corresponding to the NACO control information and scheduling request by the base station equipment and the mobile station equipment ensures the efficient transmission of the NACO control information as well as other control information even in the case where the base station equipment and the equipment

- 17 022843 mobile stations perform communication by using a wider frequency range composed of a plurality of component carriers. The effective exchange of these pieces of control information between the base station equipment and the mobile station equipment allows the provision of a mobile communication system and a mobile communication method that take into account ensuring a greater amount of resources used in communication.

All or part of the base station equipment and the mobile station equipment in the embodiments can be implemented as an LSI (large integrated circuit), which is typically an integrated circuit. The functional units of the base station equipment and the equipment of the mobile station may individually be formed as chips, or all or part of the functional blocks may be integrated into the chip.
